Study: Rwanda is the most welcoming country in East & Southern Africa

All tourism publications seem currently to be talking about Bolivia as the most unfriendly country for tourists in the world and Iceland as the most friendly country for tourists, so I had a look how the World Economic Forum (WEF) acutally assesed the friendliness towards foreign tourists in East and Southern Africa.
According to the Travel & Tourism Competitiveness Report 2013, in which the WEF compared the (un)friendliness of 140 countries, Rwanda has the best "Attitude [of population] towards foreign visitors" in East and Southern Africa. Zambia was ranked the second most friendly country in the region, followed by Uganda and South Africa.
